I want to discover printers on worker thread

@eskimo i accepted my reply by mistake. And there is no option to undo it now.

Hi @eskimo I am looking for all printers connected to ios device . i want to discover the printers using worker thread , so that whole print operation in my application can happen on worker thread using UIPrintInteractionController's Print method (in print method of UIPrintInteractionController , i need to pass UIPrinter instance ,which i want to discover on worker thread)

I have mentioned my end goal in reply above (which is to do whole print operation in worker thread) . If not using cups , is there any other way to discover all the printers connected to ios device. If there is any other method to do this , using Bonjour service or any other api , can you please guide me how to do that ?

Thank you for your response. However, I’m curious—if ByteNoCopy isn’t meant to be used this way, what would be a possible scenario for its use?

If I just create NSString from byteNoCopy and not modify value in bytes from cpp . Instead if the value changes in cpp, I will create a new NSString . Then, this approach suppose to work ? or will still something could go wrong?
